Everyone hopes to have a high-quality sleep at night, but numbness in the hands during the middle of the night can affect sleep quality. People may ask themselves: why do my left hand go numb at night? It could be due to incorrect sleeping posture, leading to problems with local blood circulation. If this occurs frequently at night, it could be a sign of certain diseases, such as stroke or cervical spondylosis, which should be taken seriously.
If there is a problem with sleeping posture, it can be quite simple. If the sleeping posture is incorrect and nerves in the limbs are pressed, it can lead to numbness in the hands. For example, some people like to sleep with their hands under their pillow, which can be uncomfortable. Typically, changing the sleeping position will make the numbness disappear.
Numbness in the hands during sleep can be an indication of various diseases:
1. Cervical spondylosis can cause numbness in the hands and feet. This condition is more common in middle-aged and elderly individuals As. people age, some organs undergo degenerative changes. Many patients may experience numbness in the elbows, soreness in the shoulder muscles, pain in the upper limbs, and limited range of motion. It is essential to take this seriously.
2. Hand numbness could also be caused by a stroke, which is more common in middle-aged individuals over 40 years old. Some patients may also experience symptoms such as limb numbness, dizziness, and feeling unbalanced. Those with hypertension, hyperlipidemia, or diabetes should be particularly vigilant to prevent the development of hand numbness.
3. Hand numbness could also be a symptom of menopause syndrome in women. During menopause, women may experience hand numbness, which gradually improves after menopause ends.
4. Thoracic outlet syndrome can also cause hand numbness due to tension and pain in the scalene muscles. Tightness in the anterior and middle bundles can stimulate the brachial plexus, leading to hand numbness. Many people only focus on cervical spondylosis and overlook this issue, resulting in persistent symptoms. Pressure points can be found in the scalene muscles.
5. Injuries to the forearm extensor muscles, which are located near the lateral epicondyle of the humerus, can also cause hand numbness by compressing and stimulating the nerves. This type of numbness is often more pronounced at night, and only the forearm and hand may be affected.
6. Injuries to the hand nerves, including the ulnar nerve, radial nerve, and median nerve, can also cause hand numbness. It is important to identify the location of the compression to determine the specific syndrome, such as cubital tunnel syndrome or ulnar nerve entrapment syndrome.
Individuals experiencing numbness in their left hand should undergo a detailed examination at a hospital. Once a diagnosis is made, conservative treatment methods can be used to manage the symptoms. In severe cases, surgical intervention may be necessary. Additionally, individuals should prioritize healthy lifestyle habits, including proper warmth and protection against the cold.
